Intel® Pentium(R) Dual Core™ T2330 (1.60GHz/500Mhz FSB/1MB cache)
Distro: Ubuntu 8.04 Hardy (running KDE 3.5.9)
VirtualBox: 1.6.2-31466-Ubuntu_hardy (deb)
VirtualBox Guest: Windows Vista Home Premium
The VirtualBox Guest Additions: Installed
Attached is a screenshot of my snapshots:

these snapshots are taking up 8.7GB of space on my HD. They served me when I was setting up my Vista Machine...but now I just want ONE snapshot that contains my vista in pristine condition...application data is being saved outside the vm and is not a concern.
How do I do this???
Thanks for your help!
